Application filed December as, 191i. ser al Ire. states.

To all whom time?) concern: I

Be it known that LJorin R. DONNELLY, a citizen of the United States, residing at Fort VVayne, in the county offAllen and.

knowledge the operation of the same is at tended with excessive noise which renders the device im )racticable for man uses and among the objects of my invention are to provide a simple burner which shall be capable of operation with a minimum of noise, and which shall maintain its vaporization of the fuel in a novel manner.

In the drawings I illustrate one manner of carrying out my invention in practice, 1n.

which- Figure 1 is a plan view ofa device embodying my invention; Fig. 2, a vertical section of the same; Fig. 3, a plan view of the baffle gate or shutter, of the U-shaped member which for the baffle gate or shutter.

forms a seat Referring to the drawings is a tubular member or bushing which forms the chamber of the device in which heat is produced which continuously vaporizes the fuel in coil 18 more fully explained hereafter, and the forward extremity of which bushing-is provided with an annular flange 11. Ribs or other suitable devices 12 are provided at suitable intervals on the exterior of member 10 which serve to space member 10 from member 13. Member 13 is preferably cylindrical or tubular in form and terminates at its rear end in a hood 14, which hood serves to inclose the rear end of the bushing 10. A suitable gate or door 15 is provided in the side of the hood to provide access to the interior of the same, and, if desired, an opening 16 may be provided in the rear wall of the hood, a suitable door 17 serving to close the same.

Vapor coil 18 encircles member 13, the

forward end 19 of which is connected to'a suitable fuel supply or storage tank, not shown, and the rear end is connected to a suitable discharge nozzle 20 which is supported within hood 14 and is adapted to discharge vapor into the rear open end of and Fig. 1, a plan view member 10, a valve 21 servingto control the discharge of vapor fromthe nozzle.

The forward end of member 13 is suitably spaced from flange 11 on member 10 in order to admit air into space or passageway 22 between members 10 and 13, and a suitable collar on member 13 is movable to regulate the annular opening or space between member 13 and flange 11 in order that the entranceof air into passageway 22 may be regulated. The air entering passageway 22 passes through it into hood 1 1 and into member 10 where it mixes with the vapor discharged from nozzle 20.

arnr ora on A tubular member-'23, having a flange 2-1 at its rear end, is connected to the forward end of bushing 10, flange 2 1 being similar to, flange 11 and the two flanges being connected in any suitable manner, as by bolts 25.

In connecting the two flanges 11 and 24, a U-shaped flat spacing member s, which is perforated at s to receive bolts 25, is inserted ,between the adjacent faces of. the flanges. The curved portion of the inner edge of member s is concentric with the inner periphery of chamber 10, and in the opening of said member, when the parts are assemled, is removably inserted a gate or shutter 27. This gate or shutter seats in the opening in member a and it is provided with one or more 0penings 28, which in the assembled position of the parts, closely approach the inner. surface of the bushing. The location of the opening or openings 28 relative to the inner surface of the bushing may be varied from that above described and shown, but I have found that the best results are attained byarranging the opening or openings 28 in gate or shutter 27 so that there shall be a substantially continuous annular slot in the gate, the outer edge .of

gate 27 having place. Vapor is then permitted to discharge again from nozzle 20 into chamber 10 and the same flows through the perforations in gate'or shutter 27 and is discharged at the forward end of member 23, where it may be ignited. While this combustion of the vapor forwardly of the gate or shutter is continued, gate 27 tends to retard somewhat the flow of thevapor from bushing 10 into member 23.- T'he'red heated portion of the wall of bushing 10 remains constantly in thatcondition while the vapor is burning at V the forward end of member 23, a portion of the vapor within theibushing being con-' sumed therein to maintain the necessary heat, and the continuously red heated bushing 10 maintains continuous vaporization of the fuel which flows through the vapor coil. By opening door 17 and looking into bushing 10 while the device is in operation" the entire rear surface of gate 27 and the Wall of bushing 10 are visible to the eye. The vapor is seen discharging from the nozzle, and the retarded vapor acts as a cushion to that discharging from the nozzle with the result that a sufiicient quantity of the vapor which flows through bushing 10 is combust-' ed on the red heated surface of the same to maintain said surface in its red hot condition. The bluish and white flame which occurs atthe forward end of member 23 is entirely absent within bushing 10 and there is visible only the glowing surface of the red heated wall of the bushing in addition to the gate and spray of vapor from the nozzle. i I 7 Member 23 may be extended several feetas mu'ch'as fifteen feet and the vapor combusted at its forward end yet the red heated condition of bushing 10 remains continuously and continuous vaporization of, the fuel in the coil is maintained. This red heated condition of the bushing is maintained by a partial combustion of the vapor Within it, the gate acting as a baflier to the vapor passing through the bushing.

The flame at the forward end of member 23 is intensely hot and may be used for a large variety of purposes, such as supplying heat for boilers, furnaces and the like. ,The flame is clean and the device operates with comparatively little noise and is not bothered with carbon either in the coil or discharge nozzle. The absence of noise/1n 1ts operation gives the device a decided advantage for many uses.

1 have found that 1may tap bushing 10' adjacent gate 27 and insert a pipe therein by which 1 may conduct gas from the bushing which will burn in a burner at the end of the pipe with an intensely blue and hot flame. Or I may extend the forward end of member 23 for several feet and combust the gas at such distant point without interfering in the least with the maintenance of the red heated condition of bushing 10.

I intend to apply the gate or shutter to any liquid fuel burner where the same shall be applicable, hence I do not wish to be limited to the specific'constructionof burner nor the form of gate or shutter, nor the ex act location thereof heretofore described and illustrated in the rawings, 1t being-apparent that many modifications in the structure of the gateland in its mode of attachment are possible. What I claim is: In a device of the class described the combination of a vaporizing coil, a bushing within the coil, a nozzle connected to the coil for discharging vapor therefrom into the bushing and a perforated gate within the bushing for restricting the flow of the vapor therethrough.

In witness whereof I hereunto sign my name this 22d day of December, 1911.
